Daniel Radcliffe – Harry Potter, Harry Potter

While Daniel Radcliffe’s list of best movies is long and notable – with entries like Swiss Army Man and Weird: The Al Yankovic Story – he will always be known first and foremost as The Boy Who Lived.

Sarah Jessica Parker – Carrie Bradshaw, Sex and the City

I’m sure Carrie Bradshaw inspired many women to become writers, and I know she left many of us fantasizing about living out our lives in New York City.

Along with playing the writer in the OG series Sex and the City , SJP has also portrayed her in two movies and the series And Just Like That .

Emilia Clarke – Daenerys Targaryen, Game of Thrones

Khaleesi, Mother of Dragons, Daenerys Targaryen, those are all the names Emilia Clarke’s dragon rider went by in Game of Thrones , and she gave an absolutely commanding performance as her.

Mark Hamill – Luke Skywalker, Star Wars

He was the face of the original trilogy, and you can’t think about Star Wars without thinking about Mark Hamill and Luke Skywalker. While the actor is well-known for other roles, especially in the world of voice acting, his most prominent part has to be this.
